I had no problems loading the 144_34.bvh at 5,882K and it certainly didn't take an hour. I suspect that the issue of the hour long load time was system specific and not Poser specific because we both used Poser Pro 2010. I used the 64 bit version on Windows 7 64Bit and they loaded but the rotations were off for Mike 3. I guess I can try again with Aiko and see how well she does.
